John McCain: 'I'm the Same Person'

Despite his seeming resentment towards Obama's policies, McCain said he harbored no ill feelings towards the president himself.

"I'm the most fortunate man in America and for me to look back in anger at the wonderful life and experience that I've had would be foolish," he said. "[Obama] won fair and square. ... I accept the verdict of the American people and it's been a great honor for me to have served."

During his primary campaign against challenger J.D. Hayworth, McCain came under attack for moving to the right on several issues, including immigration reform and don't ask, don't tell" -- a policy on homosexuals serving openly in the military. Criticism that McCain rejected.

"I haven't changed on Don't Ask Don't Tell," he said. "On climate change I've said we have to have nuclear power which this administration has rejected."

McCain Answers Charges of 'Selling Out'

However, McCain conceded that he did change his stance on immigration, but said it was because he was following what the voters wanted.

"On immigration that was shifted with, frankly because the American people spoke they want the border secure," he said.

In an interview on April 3, 2010, McCain told Newsweek's David Margolick that he "never considered myself a maverick," prompting "The Daily Show's" Jon Stewart to skewer him, saying, "It's like 'I Can't Believe It's Not Butter' saying 'I never believed I was butter!'"

McCain explained what he meant in his recent interview with "Nightline."

"I consider myself a person who stands up for what they believe in," he said. "When I was against President Bush on a number of issues I was called a maverick. When I was against President Obama, then I'm called a partisan. What I was trying to say -- I'm the same person."

When asked if he would ever run for president again, McCain said it was out of the question, noting that he "wasn't getting any younger."

"No. Nope. I've run twice and what was that old line by some southern politician, 'There is no education [better] than two kicks of a mule' -- the second kick."
